Abstract

A multi-use disposable set (MUDS) has at least one syringe having a proximal end and a distal end spaced apart from the proximal end along a longitudinal axis. The MUDS further has a plunger reciprocally movable within a syringe interior between the proximal end and the distal end. A manifold is in fluid communication with the distal end of the at least one syringe. At least one valve is in fluid communication with the syringe interior. The at least one valve is operable between a filling position for filling the syringe interior with fluid and a delivery position for delivering the fluid from the syringe interior. At least one connection port is in fluid communication with the manifold and the syringe interior when the at least one valve is in the delivery position. A multi-fluid delivery system having the medical convector and MUDS is also provided. Various features of the MUDS system are also described.

First claim

1 . A multi-use disposable set (MUDS) comprising:
a plurality of syringes, each syringe having a proximal end and a distal end spaced apart from the proximal end along a longitudinal axis, and a plunger reciprocally movable within a syringe interior between the proximal end and the distal end; a manifold in fluid communication with the distal end of each of the plurality of syringes; at least one valve in fluid communication with the distal end of at least one of the plurality of syringes, the at least one valve operable between a filling position for filling the syringe interior of at least one of the plurality of syringes through a filling port and a delivery position for delivering fluid from the syringe interior of at least one of the plurality of syringes through the manifold; and at least one connection port in fluid communication with the manifold when the at least one valve is in the delivery position.

2 . The MUDS of claim 1 , wherein the at least one connection port is provided on a frame connected to at least one of the plurality of syringes.

3 . The MUDS of claim 1 , wherein the at least one connection port is in fluid communication with the manifold through a delivery line.

4 . The MUDS of claim 1 , further comprising a waste port in fluid connection with a waste reservoir.

5 . The MUDS of claim 1 , wherein each of the plurality of syringes comprises a filling line with a spike configured for connection to a bulk fluid source, and wherein each fluid line is configured for filling the syringe interior through the manifold when the at least one valve is in the filling position.

6 . The MUDS of claim 1 , wherein the at least one valve comprises a slot for engagement with a blade that rotates the slot between the filling position and the delivery position.

7 - 13 . (canceled)

14 . A multi-use disposable set (MUDS) comprising:
at least one syringe having a proximal end and a distal end spaced apart from the proximal end along a longitudinal axis, and a plunger reciprocally movable within a syringe interior between the proximal end and the distal end; a manifold in fluid communication with the distal end of the at least one syringe; at least one valve in fluid communication with the syringe interior, the at least one valve operable between a filling position for filling the syringe interior with fluid and a delivery position for delivering the fluid from the syringe interior; and at least one connection port in fluid communication with the manifold and the syringe interior when the at least one valve is in the delivery position.

15 . The MUDS of claim 14 , wherein the at least one valve has a valve head with a slot recessed into the valve head.

16 . The MUDS of claim 15 , wherein the slot is shaped to receive at least a portion of a coupling mechanism for rotating the at least one valve between the filling position and the delivery position when the coupling mechanism engages the slot of the at least one valve.

17 . The MUDS of claim 15 , wherein the slot narrows in a direction from a distal end of the valve to a proximal end of the valve.

18 . The MUDS of claim 14 , wherein the at least one valve is rotatable within between the filling position and the delivery position.

19 . The MUDS of claim 14 , wherein, in the filling position, the at least one valve is operable for filling the syringe interior through a filling port in fluid communication with a bulk fluid source and in the delivery position, the at least one valve is operable for delivering fluid from the syringe interior through a discharge outlet in fluid communication with the manifold.

20 . The MUDS of claim 14 , wherein the at least one connection port is provided on a frame connected to at least one of the plurality of syringes.

21 . The MUDS of claim 14 , wherein the at least one connection port is in fluid communication with the manifold through a delivery line.

22 . The MUDS of claim 41 , wherein the at least one connection port has a waste port in fluid communication with a waste reservoir.

23 . The MUDS of claim 19 , further comprising a filling line having a spike for connection to a bulk fluid source, wherein the fluid line fills the syringe interior with fluid through a filling port when the at least one valve is in the filling position.

24 - 32 . (canceled)

33 . A multi-use disposable set (MUDS) comprising:
a plurality of syringes, each syringe having a proximal end and a distal end spaced apart from the proximal end along a longitudinal axis, and a plunger reciprocally movable within a syringe interior between the proximal end and the distal end; a manifold connected to the distal end of each of the plurality of syringes; the at least one valve associated with the manifold, the at least one valve operable between a filling position for filling the syringe interior of at least one of the plurality of syringes through a filling port and a delivery position for delivering fluid from the syringe interior of at least one of the plurality of syringes through the manifold; at least one filling line in fluid communication with the interior and the syringe interior of at least one of the plurality of syringes when the at least one valve is in the filling position; and at least one connection port in fluid communication with the manifold and the syringe interior of at least one of the plurality of syringes when the at least one valve is in the delivery position, wherein the at least one valve has a valve head with a slot recessed into the valve head, wherein the slot is shaped to receive at least a portion of a coupling mechanism for rotating the at least one valve between the filling position and the delivery position when the coupling mechanism engages the slot of the at least one valve.

34 . A syringe/manifold configuration comprising:
at least one syringe having a conical distal end having a syringe fluid port; and a manifold comprising at least one manifold conduit, wherein the manifold conduit is in fluid connection with a main fluid channel and a conduit syringe attachment end, wherein the conduit syringe attachment end is in fluid communication with the syringe fluid port of the at least one syringe, wherein the conduit syringe attachment end of the at least one manifold conduit is in fluid tight connection with the syringe fluid port of the at least one syringe.

35 . The syringe/manifold configuration of claim 34 , wherein the at least one manifold conduit comprises a filling port configured for fluid communication with a MUDS fluid line, a discharge outlet in fluid communication with the main fluid channel, and a valve receiving cavity, wherein the discharge outlet and the filling port are in fluid communication with an interior of the at least one syringe through a valve assembly in a valve receiving cavity.
